It's not precisely stated in the GP, but most probably that one. Background: Russian and Belarusian spelling of names are slightly different, the latter being orthographically closer to the phonetic value. (The current Belarusian president-for-life is globally known as "Alexander Lukashenko", which is a transliteration from Russian; the Belarusian spelling, again transliterated, is "Alyaksandar Lukashenka". For the originals, see his Wikipedia page.)
N.B. I'm writing this as a non-expert in either of the languages, but I can read Russian.
